The injury bug has bitten the Timbers' center back position again.

Futty Danso will miss six weeks with a left foot injury.

Danso was walking around with a boot on his left foot during the team's training session last Friday. Danso likely injured his foot while playing against Norwich City in the exhibition game July 24.

Danso, 30, has appeared in 10 MLS games (nine starts) this season. He joins a growing list of center backs who have been injured this season.

Mikael Silvestre suffered a season-ending torn ACL in his left knee in the Timbers' scoreless draw against New England May 2. David Horst is progressing with rehabilitation after sustaining a broken bone in his right leg during the Timbers 2-0 win against Houston April 6. Current starter Andrew Jean-Baptiste missed a game with an injury earlier in the season.

Rauwshan McKenzie, who was on the bench in the Timbers loss at San Jose July 27, will likely remain the backup for starters Jean-Baptiste and Pah Modou Kah.
